The aims of this study were twofold: i) to investigate changes in the sensory characteristics and consumer preference of diluted espresso drinks according to different dilution rates; ii) to compare the physicochemical characteristics between diluted espresso coffees, using the preferred coffee of this study and commercial products from coffee shop chains. Descriptive analysis using a 15 cm line scale, and a consumer preference test were carried out by 6 trained panelist,; and 50 consumers (F=39, M=11), respectively. Appearance (transparent, black), odor (bitter, rich), taste (bitter, burnt, astringent, umami, sour), and mouth-feel (aftertaste, body, coarseness, oily, roughness, soft-swallowing) were significantly different among the 3-, 5-, 7-, 9-, and 11-times dilution rates. In particular, the sensory characteristics associated with mouth-feel showed obvious differences with the dilution rates. In the consumer preference test, the 9-times diluted espresso had the highest preference, whereas the 3-times diluted espresso showed the lowest preference. Moreover, the 9-times diluted espresso demonstrated similar physicochemical characteristics such as pH, sugar content, and total solid content to those of the commercial diluted espresso drinks from coffee shop chains. In conclusion, the sensory characteristics and consumer preference of the diluted espressos were influenced by the dilution rates.

This study investigated the sensory characteristics of adlay tea favorably consumed by Korean consumers and analyzed the drivers behind for liking or disliking adlay tea. Six adlay tea products showing the highest market share in South Korea were selected. Sensory properties of the six products were analyzed using generic descriptive analysis. Among these, four products were further selected for consumer taste acceptance test. Sensory lexicons of adlay tea were developed by trained panelists, and the sensory characteristics of each adlay tea product were measured based on the perceived intensities of these attributes elicited from the samples. In the consumer taste acceptance test, frequent tea and coffee drinkers participated. Consumers rated the acceptance of each tea product on a 9-point hedonic scale and evaluated the reasons for liking or disliking each product based on the check-all-that-apply method. Analysis of Variance, principal component analysis, frequency analysis, and correspondence analysis were utilized for statistical analysis. Twenty sensory attributes were developed in order to characterize the six adlay tea products. The results of the descriptive analysis showed that attributes such as viscosity, black soybean flavor, goso flavor, peanut flavor, seaweed flavor, green, and presence of chunks were key factors differentiating the adlay tea products. In the consumer taste test, roasted flavor, goso flavor, peanut flavor, and presence of chunks were positive drivers for liking the adlay tea products, whereas seaweed and green flavors were negative attributes that drove consumers away.

This study was conducted to identify the sensory characteristics of the Korean traditional confectionery, dasik, prepared under different conditions and to compare their consumer acceptance in Korea. To accomplish this, descriptive analysis of eight samples prepared using two types of rice cake powder, dasik (Rflour, Rflour_Omija), brown rice powder red ginseng dasik (Brice_Ginseng_P), pinepollen dasik (PineP), black sesame dasik (BSesame), bean dasik (Rbean), and two types of mungbean starch dasik (Starch_Omija, Starch_Greentea), was conducted by ten trained panelists. In addition, 81 consumers evaluated the overall acceptance (OL), acceptance of appearance (APPL), odor (ODL), flavor (FLL), and texture (TXTL) of the samples using a 9-point hedonic scale, as well as the perceived intensities of sesame flavor, sweetness, and hardness using a 9-point just-about-right (JAR) scale. Partial least square- regression (PLSR) indicated that the BSesame and Rbean samples, which had significantly (p<0.05) high roasted sesame, burnt, greasy, glossy, and cooked chestnut flavor scores, had the highest acceptability and consumer desire scores. Additionally, the PineP and Rflour_Omija samples, which had relatively high particle size, transparency, roughness, spoiled tofu, fermentation and raw rice flavor scores, were the least preferred samples. Therefore, roasted sesame, burnt, greasy, glossy, and cooked chestnut flavor attributes were considered drivers of "liking" whereas particle size, transparent, roughness, spoiled tofu, fermentation, and raw rice flavor attributes acted as drivers of "disliking" among consumers.

남해산 생마늘 및 흑마늘의 일반성분 분석, 아미노산 함량 및 마늘의 주요 황 함유 생리활성물질인 수용성 $S$-allyl-L-cysteine(SAC) 및 지용성 diallyl-disulfide(DADS)의 함량을 분석하여 발효 전후 이들 성분에 대한 함량 변화를 비교하였다. 일반성분의 함량은 생마늘과 자가숙성발효마늘에서 큰 변화가 없었다. 흑마늘 내의 17종 아미노산중 13종 아미노산 함량이 증가하였다. 특히 함황아미노산인 cysteine 및 methionine의 함량(mg/100 g)이 각각 $295.25{\pm}5.08$에서 $381.86{\pm}14.86$로, $47.2{\pm}3.92$에서 $66.6{\pm}1.08$로 증가하였고, histidine의 함량(mg/100 g)은 $319.19{\pm}5.42$에서 $796.62{\pm}7.01$로 크게 증가하였다. SAC 및 DADS의 함량(${\mu}g/g$)은 $245.35{\pm}1.35$에서 $522.51{\pm}1.19$로, $0.275{\pm}0.015$에서 $8.710{\pm}0.45$로 각각 2배와 30배 이상으로 생마늘에 비하여 흑마늘 내의 함량이 매우 큰 폭으로 증가하였다. 이러한 현상은 자가숙성발효라는 제조과정에서 생마늘의 alliin이 1차적으로 효소와 기타 화학적 반응에 의해 allicin으로 전환된 후, allicin으로부터 다른 일련의 복합적인 화학반응에 의하여 많은 양의 SAC 및 DADS가 생성된 결과에 의하여 나타났다고 할 수 있다. 또한 자가숙성 발효 과정 중 이러한 SAC 및 DADS 등과 같은 마늘 내 함황화합물들의 지표물질 생성 확인은 인체에 유익한 생리활성을 보유한 많은 종류의 다른 함황화합물들이 동시에 흑마늘 내에서 생성되었음을 암시한다. 그러나 흑마늘의 제조과정은 85~95%의 습도, $60{\sim}70^{\circ}C$에서 40여일 정도 장기간의 숙성이 필요하다. 이러한 숙성과정은 특정 미생물 또는 효소를 이용하여 단축할 필요가 있다. 또한 SAC 및 DADS 등과 같이 생리활성이 높은 함황 화합물들의 함량을 증가시킬 수 있는 새로운 가공법에 대한 연구가 필요하다.

Pork from Jeju black pig (population J) and Berkshire (population B) has a unique market share in Korea because of their high meat quality. Due to the high demand of this pork, traceability of the pork to its origin is becoming an important part of the consumer demand. To examine the feasibility of such a system, we aim to provide basic genetic information of the two black pig populations and assess the possibility of genetically distinguishing between the two breeds. Muscle samples were collected from slaughter houses in Jeju Island and Namwon, Chonbuk province, Korea, for populations J and B, respectively. In total 800 Jeju black pigs and 351 Berkshires were genotyped at thirteen microsatellite (MS) markers. Analyses on the genetic diversity of the two populations were carried out in the programs MS toolkit and FSTAT. The population structure of the two breeds was determined by a Bayesian clustering method implemented in structure and by a phylogenetic analysis in Phylip. Population J exhibited higher mean number of alleles, expected heterozygosity and observed heterozygosity value, and polymorphism information content, compared to population B. The $F_{IS}$ values of population J and population B were 0.03 and -0.005, respectively, indicating that little or no inbreeding has occurred. In addition, genetic structure analysis revealed the possibility of gene flow from population B to population J. The expected probability of identify value of the 13 MS markers was $9.87{\times}10^{-14}$ in population J, $3.17{\times}10^{-9}$ in population B, and $1.03{\times}10^{-12}$ in the two populations. The results of this study are useful in distinguishing between the two black pig breeds and can be used as a foundation for further development of DNA markers.

딸기에 발생하는 흰가루병과 점박이응애는 수확기 문제되는 주요 병해충이다. 딸기 수확기 병해충방제를 위해 적용 약제를 처리하지만 최근에는 소비자의 요구에 따라 친환경적 병해충 방제 방법이 요구되고 있다. 딸기 정식 후 자외선 램프(ultraviolet B, UV-B)를 이용한 친환경 병해충 방제효과를 조사하기 위해 수확기 토경과 수경재배로 2년 동안 시험을 수행하였다. 설향, 킹스베리, 두리향 품종을 정식하였으며 UV-B 램프+멀칭 종류(흑색, 녹색, 빛반사시트[light reflection sheet, LRS])별 4처리로 시험을 수행하였다. 처리는 UV-B+흑색 또는 녹색 멀칭, UV-B+흑색 또는 녹색+LRS, 무처리로 하였다. UV-B 램프 처리에 의한 흰가루병은 모든 품종에서 65% 이상의 방제효과를 보였다. 점박이응애 성충밀도는 UV-B+흑색 또는 녹색+LRS 멀칭 처리가 다른 처리보다 가장 낮았다. 따라서 딸기 수확기에 UV-B 램프 처리는 식물체에 미치는 영향도 적으며 흰가루병과 점박이응애 밀도를 낮추는 데 효과적인방제방법이될수있다.
